A library of novelchiral biphenol-based diphosphinite (BOP) ligands was designed and created. These BOP ligands were applied to a Pd-catalyzed intermolecular allylic etherification reaction, which provided a key intermediate for the formaltotalsynthesis of (−)-galanthamine with 97% ee in 97% yield.
